From the project

Universal JTAG/SWD/UART adapter based on FT2232H

- USB Type-C connector - 1.8V - 5V traget supply - JTAG and SWD support on channel A, UART support on channel B. - ESD protection of USB and of target - Integrated power section, to power target from the adapter (5V/3.3V/2.5V/1.8V available) - Similar pinout to the standard found on commercial JTAG/SWD adapters, with the addition of UART pins - JTAG/SWD programming with simultaneous UART communication - LEDs for USB power, Target power, SWD interface, Activity, and RX&TX of the UART
